5. (20 points) Hole diameter data for 20 samples (sample size = 5) result in n = 5; x =0.00109; R = 0.00635; ox = 0.00273 (a) If the specifications are at 0 + 0.01, calculate Cp and Cpk. (b) Is the process mean maintained in the center? (c) Approximately how many % of the specification band has been used up? (Hint: This can be calculated as 1/Cp). (d) Is this process capable of meeting the specifications? (Note: to meet the spefications, Cpk has to be greater than 1.33)
